scope:

This Standard specifies portable insulation resistance testers of built-in battery type, having a rated output voltage not exceeding 1000 V, which are used for the measurements of the following a) to e).

a) Insulation measurement of low voltage distribution path The insulation measurement of paths and devices which are powered off in a distribution system up to 1 000 V a.c. and 1 500 V d.c.

b) Insulation measurement of device, appliance, component, etc.

NOTE: The photovoltaic array not in power generating state corresponds to an appliance or a component.

c) Insulation measurement of high-voltage equipment

d) Insulation measurement of photovoltaic array in power generating state by short-circuiting P-N terminals

e) Insulation measurement of photovoltaic array in power generating state without short-circuiting P-N terminals

NOTE: The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

IEC 61557-1: 2007 Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c.-Equipment for testing, measuring or monitoring of protective measures-Part 1: General requirements

IEC 61557-2: 2007 Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c.-Equipment for testing, measuring or monitoring of protective measures-Part 2: Insulation resistance (overall evaluation: MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
